Snapping points for cal

[Discus84]

 

How to snap this point for 'cal function.

I'd like to divide the space.

((int+int)-x)/y

I don't know the syntax to acquire this intersection .

That formula does not make sense, a int will return at least a X & Y values. Not sure what the answer is your looking for. Post a before and after dwg.

its straightforward to do 'cal and input (2+2) for line length.

What I'd like to do is:

0) Invoke offset then 'cal

1)point with a mouse to an intersection of two lines and  for the 'cal function to grab it as a location

2) point to other intersection ' cal grabs it as a second point and calculates the  distance between two.

3) 'cal will run the rest of equation 

 

'cal(grab one point+grab second point)/ offset by the distance=my answer

 

I've seen it done in Autocad , just cant seem to make it work in A12..

Write it as a lisp rather than use Cal, as it needs points already picked.

 

Show a before and after.

What do you mean?

Maybe just me I don't understand what it is your trying to achieve as final result, are you trying to trim all the line work ? As in two wall join as a tee, that exists out there.

Hey, 

Try :

1)-line

2)'cal

(cur+cur)/2 

Line snaps in the middle of the (acquired by mouse) points.

Instead of writing "int" for experession the correct syntax is "cur"

 

Thanks!

Not sure but M2P is built in and can be used in the middle of commands, eg "LINE M2P pick 2 points and line starts from the mid point of the 2 points. No need for Cal.

 

In lisp another way.

 

(setq mp (mapcar '* (mapcar '+ pt1 pt2) '(0.5 0.5)))

(setq mp (mapcar '* (mapcar '+ (getpoint "\nPick 1st point ") (getpoint "\nPick 2nd point ")) '(0.5 0.5)))

 

I still think if you show the final result would be a good idea not just a single step some where in code.
